ELECTRODE BOILER AND METHOD FOR CONTROLLING SAME

摘要

An electrode boiler of the present invention comprises: a tank in which a heat medium is stored, and which has an inlet port and an outlet port for the entry and exit of the heat medium; a plurality of electrode rods arranged in the tank to heat the heat medium; and a current control device which adjusts the contact area between the heat medium stored in the tank and the electrode rods to control a current, whereby simplifying the configuration thereof and reducing the manufacturing cost. The electrode boiler of the present invention is appropriate for manufacturing a small-sized electrode boiler.
